MOTOR.

To all whom t may concern: y

Be it known that I, ANDREW C. ZWARIGH, a subject of the Czarof Russia, residing at Homestead, county of' Allegheny and State of Pennsylvania, have invented certain new and useful Improvements yin Motors, of which the following is a specification.

This inventionv relates to motors for driving machines orfor other purposes wherein found applicable, 'morev particularly to the type of motor disclosed in'Letters Patent No. 1,179,599-gran'ted to me'and that dislclosed in applicationfiled by me October 18th, 1916, Serial No. 126,301, and has for its object, besides the objects and advantages set Aforth in the patent and application referred to, further aimsy to provide means, in

a manner ashereinafter setforth, to facili- -tate the changing of an intermittent rotor motion -into la' continuous one,'fsa'1d change of such" motion being the primary object of the patent and the application heretofore re ferred to. 1

Further objectsof the invention are to its conefficient in l its use, readily set up and comparatively vinexpensive 'to manufacture.

lVith the foregoing and other objects in view lthe invention consists ofl the novel construction, combination and arrangement of arts as hereinafter more specificallyr described and illustrated in the accompanying drawings, wherein is shownan lembodiment of theinvention, but it is to be understood vthat changes, variations and ymodifications can 'be rresorted to which come within the scope oflthe claim hereunto appended.

In the drawings `whereinl like reference denote corresponding vparts Figure 1 is a sectional elevation of a motor in accordance with this invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a sideelevation of a modified form of motor in accordance with this invention. l Fig.v 4 is a detail of the pawl.l

Referringtothe 'drawings in detail 1. denotes a stationary shaft provided with `a crank 2 intermediate its ends and which is mounted in a pair of uprights 3.

Rotatably mounted on the shaft 1, between the uprights 3, is a pair of lateral shafts 4, 5, which form a part of the rotor` K vpecificaton of Letters Patent. Patented Aug, 21, 1917, Application led March 3, 1917'. Serial No. 152,299. i

. 6 and the said shafts 4, 5, 'arehollowl through whichy extends the shaft 1.

The crank 2 .and said shaft l, are positioned within the rotor and the latter is formed of two sections, one ofthe sections of the rotor consists of a plate 7y having` the annularmember'S, by securing .devicesl v 10. rllhe rotor 6 revolves upon the stationary shaft 1.

Mountedl upon the crank 2 and eccentriv`cally disposed withrespect to the rotor y6, is a disk 11, having the inner ends 12, of a se.

ries of shifting elements 13,.,14, 15 loosely connected therewith.

The outer ends of the shifting elements are anchored as at 17, to the inner face of and 16 the annular member 8,r and the said outer ends are arranged equi-distant with respect to each other. Each of said shifting elements consists olf a contractible and expansible coil spring.

Fixed to one side of therotor, is a ratchet wheel 23 and associating therewith is a pair of actuating members 24, 25,. and which are connected to a lever 26. The member 24 is connected to the lever 26 -as at 27 and the member 25 is connected to the lever 26 as at 28. The lever 26 has a pair of pivoted pawls 29, 30, which extend in opposite vdirection with respect to each other. The ratchet wheel, actuating members', leverand-pawls are termed a .driving element and when one of said members isoperated it is adapted-to intermittently rotate the rotor in one direction and when the othermember is actuated it is adapted'to rotate the rotor in the opposite v direction.

l The shaft 5 is provided with a pulley or gear 31 whereby the rotor .can be coupled with the machine or other device and operate the same. f

Theishifting elements 13 to 16 are employedto set of a continuous rotary motion for the intermittent drive, that is to say when the rotor is intermittently operated by the driving element the shifting elements successively expand or contract.. During the contracting movement thereof it causes the rotor to revolve and this movement is had in view of the fact that the disk 11 is eccens trically disposed with respect to the rotor nectech IBesides the elements referred to which are employed inthe motor shown in 'shaft 1 provided with the crank 2, shifting elements 13 to 16, disk 11 mounted on the crank 2 and to which the inner ends of the shifting elements 13, to 16 are loosely con- Fig. 1, the motor illustrated in Fig. 3 includes a pair of elongated rectangular plates 32, 33,which areV secured to opposite sides of a circular band 34 having peripheral teeth' 35. The rectangular plates or carriers y32, 33, are rotatably mounted on the shaft 1 and the ends of the plates or carriers 32, 33, terminate inwardly with respect to the teeth 35l of the circular band. v

The shifting elements 13 to 16 have their outer ends connectedto the inner face of the'band 34.

Thewcarrier 321 is provided withashort shaft 37 and the carrier 33 with a .short shaft 38. f

Fixed to one side of the carrier 4 is a driving element constructed ina manner similar to thatfreferred to with respect to the driving element employed in Fig. 1.

The foregoing elements referred. to in connection with Fig. 3 are substantially similar' to that form of motor illustrated in my application before referred to.

The shaft 4 in Fig. 1 has peripheral teeth 40 which extend just half the circumference of said shaft 4. f. j

The shaft 38 in Fig. 3 is provided with peripheral teeth 41 which extend just half the circumference of said shaft 38.

As the means forming the subject matter ofI this: application are lemployed `in connection with' the form of motor shown in Fig. 1 yor the form of motor shown in Fig. 3 is of the same construction, similar reference characters to indicate the elements of said means willbecmployed in the several figures of the drawings. Said means or mech anism..includesl`the teeth. of the' shaft 4, or the teeth ,-on'the shaft 38 and the said means or mechanism further includes a toothed quadrant 42 which is arranged at one side of the motor and whichis pivoted to a 'support, as at 43. The teeth of the quadrant 42 are indicated at 44 and are adapted to mesh with teeth 40 and. 41. Connected at one end, as at 45, to the quadrant42, is a coil spring 46, the latter having its other end anchored as at 47, to a support 48.

Associating with the quadrant 42 is a spring controlled pawl 49 which is mounted on a post 50, the latter has its inner end fixed in a bar 51, which is slidably mounted on posts 52, 53, and upon said posts 52, 53, are arranged coil springs 54.

The pawl `mechanism referred to is secured to the carrier 33 or to the plates 7 and said plates or carrier has a. slot 55 f through which is adapted to project posts;

50 due to the actio'nof the spring. 54. Posts 52, 53, are secured to the inner face :of .the plate or carrier 7 and the pawl 49k projects beyond the outer face of thesaid plate or carrier 7.

During the revolving of the rotor, in eitherform of motor shown, the teeth 40 and 41, will shift the toothed quadrant 42 in one direction. After the teeth 40 or 41,

clear the teeth- 4 of the quadrant 44 thel spring-46 will shift the quadrant 42 and the latter engagingthe'pawl 49 give an vimpulse to the ,rotor and assist the action of the shifting elements.

The spring controlled .pawl as v'the rotor` revolves will be compressed when it engages the quadrant and under such conditions will not interfere with the operation'ofzthe rotor.

What I claim is f y A vmotor'comprising a rotor, meansfor intermittently rotating said rotor, a series of expansible and contractible elements arranged within said rotor for changing the intermittent drive of the rotor into a clon-- tinuous one, and an oscillatory mechanism arranged exteriorly of andv operated in one direction by the rotor and further capable of engaging with the rotor after being operated thereby for assisting said elements in changing the intermittent drive of the rotor into a continuous one.

In testimony whereof I affix my signaturc in the presenceofI two witnesses. j
